Senolysis by glutaminolysis inhibition ameliorates various age-associated disorders

Description

A collaborative research group led by Professor Makoto Nakanishi of the Institute of Medical Science, The University of Tokyo (IMSUT), and co-researchers(※)has identified an inhibitor of the glutamate metabolic enzyme GLS1(*1) so that its administration selectively eliminates senescent cells in vivo. They confirmed that the GLS1 inhibitor eliminated senescent cells from various organs and tissues in aged mice, ameliorating age-associated tissue dysfunction and the symptoms of obese diabetes, arteriosclerosis, and NASH. The results of this research were published in "Science" on January 15, 2021. 



(*1) GLS1
Abbreviation for glutaminase 1. A type of amidohydrolase enzyme that produces glutamic acid and ammonia from glutamine.
